Abstract
Nous déterminons les coefficients de la dispersion dans des milieux poreux caractérisés par une perméabilité aléatoire corrélée en utilisant le calcul parallèle. L'écoulement de l'eau est déterminé en discrétisant l'équation de conservation couplée à la loi de Darcy sur une grille régulière et le transport du soluté inerte est simulé avec une méthode particulaire. Pour obtenir le régime asymptotique, la taille caractéristique des grilles est de l'ordre de cent longueurs de corrélation l y avec une résolution de dix mailles par longueur de corrélation.
